The more pure and holy the heart is, it will have the more quick feeling as to the sin that remains in it. The believer sees more of the beauty of holiness and the excellence of the law. His earnest desires to obey, increase as he grows in grace.
But the whole good on which his will is fully bent, he does not do; sin ever springing up in him, through remaining corruption, he often does evil, though against the fixed determination of his will. The motions of sin within grieved the apostle. If by the striving of the flesh against the Spirit, was meant that he could not do or perform as the Spirit suggested, so also, by the effectual opposition of the Spirit, he could not do what the flesh prompted him to do.
How different this case from that of those who make themselves easy with regard to the inward motions of the flesh prompting them to evil; who, against the light and warning of conscience, go on, even in outward practice, to do evil, and thus, with forethought, go on in the road to perdition!
For as the believer is under grace, and his will is for the way of holiness, he sincerely delights in the law of God, and in the holiness which it demands, according to his inward man; that new man in him, which after God is created in true holiness.
It is our duty to mortify our members which incline to the things of the world. Mortify them, kill them, suppress them, as weeds or vermin which spread and destroy all about them.
Continual opposition must be made to all corrupt workings, and no provision made for carnal indulgences.
Occasions of sin must be avoided: the lusts of the flesh, and the love of the world; and covetousness, which is idolatry; love of present good, and of outward enjoyments. It is necessary to mortify sins, because if we do not kill them, they will kill us.
The gospel changes the higher as well as the lower powers of the soul, and supports the rule of right reason and conscience, over appetite and passion. There is now no difference from country, or conditions and circumstances of life. It is the duty of every one to be holy, because Christ is a Christian’s All, his only Lord and Saviour, and all his hope and happiness.
All possessions are stained with sin, either in getting or in using them. How ready we are to turn the things we possess into occasions and instruments of sin, and to think there is no liberty or delight in their use, without abusing them! Worldly possessions are uncertain and soon pass away, like the flowers and plants of the field. That must be of the greatest worth, which is laid up in the highest and best place, in heaven. Happy are those whose hearts the Holy Spirit sets on this inheritance. God not only gives his people grace, but preserves them unto glory. Every believer has always something wherein he may greatly rejoice; it should show itself in the countenance and conduct. The Lord does not willingly afflict, yet his wise love often appoints sharp trials, to show his people their hearts, and to do them good at the latter end.
